DEVICE FOR-HEATING TIRES;

SPECIFICATION forming part of Letters Patent N0. 768,226, at d August 23, 1904.

Application filed April 20, 1904;.

T at whmn it may concern:

' purpose of setting them on old or new wheels and for other purposes, and for accurate and satisfactory work the tires or rings of iron need to be evenly and uniformly heated throughout their extent.

The object of my present invention is to produce a simple yet efiective device for con veniently and quickly heating such wagontires and similar metal bands or rings uniformly throughout theirwhole extent for the various purposes stated.

This device I style a portable tire-heater, the same being adapted to be used with and upon an ordinary blacksmiths forge, the fire of the forge serving to heat the tire or ring held within the hollow body of the device.

Other objects and advantages of the invention will be brought out and made to appear in the following specification, reference being had to the accompanying drawings, which drawings and the reference-letters marked thereon form a part of this specification.

Figure l is a front elevation of the tireheater as in use. Fig. 2 is a front view of the same with the swinging cover or lid thrown up to open the device, parts being shown in difierent positions by full and dotted lines and parts broken away. Fig. 3 is a vertical diametrical sectionof the device, taken on the dotted lines 3 3 in Figs. 1 and 2. Fig.4 is a rear view of the device, showing the operat- 1ng parts there attached, parts being shown 1n various positions-by full'and dotted lines.

away and the section being on the horiZon-' tal dotted line 5 in Fig. 2. Fig. 6 is a rear elevation of the carrying-lever for the tire and associated gear, parts being broken away.

Figs. 3, 5, and 6 are drawn to a scale larger and Fig. 1 to a scale smaller than that of Figs.

2 and 4'.

In the'drawings, A is the main part of the device, it being a circular hollow body adapted to be placed upright upon a blacksmiths forge over the fire and holding within it the tire B, Figs. 2, 3, and 5, to be heated.

C is a circular inclosing lid or cover for the space 1 within the body, it being of sheet metal or other suitable material held by hinges a to the body portion to swing in vertical directions thereon, as indicated in Figs. 2 and 3.

The body portion A is formed with an expanded part or fire-box D at its lower side or base to rest immediately over and cover the coal fire of the forge, the draft of the fire and the products of combustion passing upward in and through the space within the body, as a draft flue or chimney. Above the body A is commonly employed a short rectangular flue E, to the upper end of which is secured an ordinary sheet-metal pipe F of suitable bend or form to lead into a chimney.

The tire Bis suspended on a carrying-roller 6, Figs. 2, 3, and 5, made adjustable or shiftable in substantially vertical directions to hold tires of different diameters, the lower part of the tire in every case being low down and near the fire within the box D, as shown. A curved heat-deflecting plate 0 is secured rigidly to the inner surface of the rear plate cl of the body A a short distance above the firebox D.by a bracket 6, Figs. 2 and 3, the lower part of the tire when in place being below said plate 0, as appears in the figures. To the ends of the deflecting-plate care secured, respectively, flexible heat or current deflectors ff, these deflectors being thin strips of metal having loo'ps g g, occupied by fasteners it it, threaded in the back plate 0Z. By means of the loops and the threaded fasteners the upper ends of the deflectors f f may be held in positions of adjustment, they being bent or turned in directions toward or from the tire, according to the size of the latter, to regulate the capacity of the inner fines or heat-spaces e' next the tire.

7a 70, Figs. 2, 3, and 5, are a pair of outer flexible heat deflectors secured rigidly at points Z Z to the inner surface of the band or ring portion at of the body A and reach upward well toward the upper part of the inclosures n of said body, as shown in Fig. These deflectors are provided with loops a a and threaded fasteners 0 0, similar to the parts g g and it 71 above described, for holding them in positions of lateral adjustment, as indicated in Fig.2; These deflectors 7c are bent outward or inward, according to the diameter of the tire to be heated, all the flexible deflectors ff and 70 A; being adjusted in each case to confine the currents of heat within narrow limits and near the tire being heated.

All of the deflectors, including the rigid plate 0, have a common horizontal width about equal to the horizontal depth of the inclosnre p of the body A, to the end that when the lid or cover C is closed and in place the ascending currents of heat will be confined closely along the tire on both sides and prevented from becoming diffused throughout the entire inclosed space 19 of the body A. It is found in practice not necessary to carry the inner deflectors ff as high as the outer ones Z4 Z1, these being carried high up over the tire, as shown, leaving an opening r between their upper adjacent ends for the escape of the products of combustion.

The holding-roller b for the tire is conveniently carried at the end of a lever portion (is, pivoted ats to the rear surface of the body A, so as to swing in a vertical plane. The roller 7) is held upon a spindle t, Fig. 3, having its overhanging end extending outward from the inclosure 1) of the body A through a curved slot u in the rear plate d of the body and piercing the end of the lever G, as shown. A bevel-gear e is made rigid with the spindle t, said gear, the spindle, and the roller turning as a single rigid body in the bearing in the lever G. The lever is formed with rear- Wardly-projecting bearings w w, holding a shaft 00, provided at one end with a bevelpinion 3 to engage the teeth of the gear '0 and at the other end with a suitable handle .2

for conveniently turning the shaft. The lever G is swung on its pivot s in vertical directions to raise or lower the carrying-roller Z) to properly hold the tire, in each case the lever being held or retained in its adjusted positions by some simple detent or fastener, as a pawl 60, held by the lever with its point engaging the teeth of a ratchet Z), secured to the body A. The weight of the loaded tire and other parts tend to carry the inner end of the lever downward; but this motion of the lever will be opposed by the pawl and the lever held thereby securely in positions of adjustment.

I do not conlinelnyself to the pawl and ratchetshown. Anyothersimpleaialsuitable detent or holder for the lever would as well answer the purpose.

1 usually form the lire-box l) with a door d for the purpose of examining the lire within. The swinging cover (I is raised and lowered by means of a rope or small cable attached to an eye-screw c, the rope or cable extending upward over a pulley overhead.
